Serial No. 315,858. 1 KT 7 This invention is concernedwith mechanism for imparting vibratory'movement'to parts of the human body, and as shown is particularly adapted to vibrate a flexible j strap, the strap being in embracing contact with whatever part of the body it is desired to massage, and the vibratory'movement being imparted to the strapby alternatelypulling the ends thereof. j

The essential object is to provide a strap vibrating mechanism which will'be simple to construct, effective in operation and of comparatively light weight. 7

A further object is to provide animproved andsimpli'fied drivingarrangement between a strap to be vibrated and an electric motor.

A further objectis to provide a strap vibrating mechanism in which all parts of the mechanism maybe easily and quickly assembled, and which, though comparatively light in. weight, will be-adequately strong to withstand continued shock dueto the vibrating impulses under load.

A further object is-to'provide a support for a vibrating mechanism, by which the mechanism may be easily and firmly attached to existing parts of a dwelling house without modification of such parts.

Further objects and features will become apparent from the following description relating to the accompanying drawings, which show the preferred forms of the invention. The essential characteristics are summarized in the claims.

Fig. 5 is a side elevation showing still another form of supporting. device, and Fig. 6 is'a fragmentar sectional plan view taken along the line 6 on Fig. 5.

Referring in detail to the drawings, 1 indicates thegeneral housing for the motor and "spectively designated? and 8 carried on the which forms the? bearing for one-end of the bushing 11 and a capmember 29 respectively In the drawings, Fig. 1 is a sectionalsidevibrator gearing. Thefhousing, asshown, comprises two hollow sections, preferably castings, there being a section 2 and a section 3 suitably secured together'by means of studs}; (see particularly Fig-2)."; The studs arethreaded into the section 2 as atj5 and project through openings inthegend wall of the section V 3', the proj ections being threaded and engaged by cap nuts 6 bearing against such wall; of the housing, I cidentally support the field Fof the motor, the. field frame being. perforated. to receive the studs, as shown'in ;Fig. 2,. and there being field frame positioning nuts and spacersrer studs and engaging the fieldframeto hold 6 the' frame in longitudinally fixed position within the housing. The motor has the usual armature A, brushes Band commutator'Cfl f 1 The housing section 2has projecting from one enda hollow housingportion 10 which carries a bushing 11 near-the top thereof and armature shaft 12havinga worm formation thereon as at 13." In addition to the bushing.

bearing l l, the motor shaft has a bushing bearingfat 27 supported by a central extension of the housing section 3. Suitable shaft end-positioning threaded members 28 in the prevent excessive longitudinalmovement of the motor shaft. v v l Below the bushing 11 andextending trans versely .ofthe hollow housing portion 10 is a shaft l icarrying a worm gear 15 meshing with the worm formation 13 and suitably at ,tached to the shaft as bya set'screw 15. 'By

reason of the gearing, the shaft 14 is driven at reduced speed with relation to the motor shaft. The shaft 14' issupported by a lateral extension 16 forming part of the housing projection 10, and by a removable cap member 17 forming a side closure for the housing portion 10 and 'carryinga lateral'95 bored-out projection-18 opposite the housing projection 16. t 0

set screws 21. Assuggested in'Fig'. 3, each disc has a plurality of threaded, openings, designated 22, positioned various distances from the axis of the shaft 14. Theopenings in the disc members'20 may i be'of any convenient number" to secure the desired variety of vibrating impulse lengths x to a strap 23 which has its ends secured to w threaded pins 24-adjustably positioned relative'to the discsby reason of the plurality of" threaded openings; Each piniis threaded on opening 22 and has a cylindricalportionj2ia for engaging the respective'end of the strap and an enlargement beyond the cylindrical portion to serve as a finger piece and to overlie the adjacent portions'of thestrapto hold the strap; on the pin. The strapends, as shown in Figs. 2 and 3, comprise compara tively heavy .:.end .members 25, "preferably length being adjustable by resetting the pins.-

It will be understood that the threaded openings 22 opposite: those shown in 3 are so related to the openings shown in Fig.3 that the two pins placed in any corresponding'pair of openings will be diametrically opposed to each other and spacedequally from. the shaft axis. Thus,the vibrating impulses at the two ends of the strap will be of equal lengthfor a given setting, this The vibrating mechanismsupporting devlce, as shown 1n Figs. land 2, comprises a bracket formed at one end to underlie the .motor 'housingand being secured thereto as by means of screws 36, the otherend of the bracket being adapted to overlie a window sill or like building part, such as diagram matically indicated at W, the extreme end 7 of the-bracket being'turned down to provide p a hook effect at 37 for engaging the abrupt surface outwardly from the sill, against which the window sash is normally positioned whenfclosed. Rising from the hollow portion of the'bra'cket is an ear 38 which supports a suitable clamping screw 39,, having a shoe 40 for engaging the window sash W2, shown slightly raised. 'The clamping shoe,
